Abstract
Growth ofSelenomonas ruminantium HD4 in medium that contained 21mm d-lactate was stimulated to varying degrees by 10mm l-malate, 10mm fumarate, and 2% (v/v)Aspergillus oryzae fermentation extract (Amaferm). Amaferm treatment caused the greatest growth stimulation. Initial uptake rates (30s) and long-term uptake rates (30 min) ofd-lactate by whole cells ofS. ruminantium were increased in the presence of 10mm l-malate. Amaferm (25 μl/ml) also stimulated long-term uptake rates ofd-lactate, whereas fumarate had no effect. Initial uptake ofd-lactate was depressed in the presence of fumarate or Amaferm. When eitherl-malate, fumarate, or Amaferm was included in thed-lactate growth medium, a homosuccinate fermentation resulted and an inverse relationship was observed between growth (protein synthesis) and succinate production. Recent research demonstrated that Amaferm containsl-malate, and this dicarboxylic acid may be involved in stimulatingd-lactate utilization byS. ruminantium.
